Yesterday I sat down to install a set of new springs for the FCG in my G43
Simple enough as it doesn’t look very complicated, as I’ve been working with firearms for many years should only take about 10 minutes or so.
Well I was wrong, so uninstalled the stock springs and then started to install the new springs and the rest of the control group.
The magazine release installed easy, no issue. The issue started to come from installing the hammer and sear group.
Installed the hammer with new spring and inserted pin, assembled the sear and spring and placed it inside the housing compressing the spring arms in the slots on the pivoting arm of the sear.
Now for some reason the holes are not lining up, what I mean is when the safety is on and the safety plunger is out the sear pinhole won’t line up.
If I disengage the safety and the plunger recesses I can move the sear arm down and the holes line up, letting me out the pin in.
But this causes the safety plunger to be covered and cannot engage. Obviously an issue.
What am I doing wrong?
The hammer is seated in the correct position and lines up with holes fine, it seems the sear hits the bottom of the hammer not allowing it to sit in the correct position for the sear to be in a spot that it won’t block the safety plunger.
I’m perplexed and could use to g43 expert help.
Some pictures to help visualize
Top view looking down, hammer spring legs seated on sear pivot/grooves.
Side view of sear arm not lining up when it’s in the position it should be to allow the safety to engage.
Side view when I release the safety and am able to pivot the sear arm in place to insert pin fully. This causes the arm to block the plunger.
Hammer and spring how I have it setup, is this the correct orientation of the spring?
Any help will be appreciated, losing my mind over this. And it’s probably something extremely stupid I’m over looking.
